What does cloud computing deal with? Cloud computing deals with all the technology and support for the infrastructure of the cloud such as networking, database, storage, and management applications. Describe each of the characteristics cloud services must have. Fshared services (with standard framework and shared application programming interface (API)) - these services can be shared in order for all users to have access to them. Fstandard user interface - Web browsers to have access to the cloud services. Fself-service - Users must help themselves by self service when it comes to doing cloud services since actions are carried over the computer, not from human to human. Fservice metering - The Charge of the usage of the cloud services. Faccess over the internet - The medium of having access to the internet, as well as other places over the internet. Explain horizontal and vertical services. Horizontal Services - cloud applications, cloud storage, cloud servers, and cloud collaboration. These horizontal services are the services that are spread around horizontally as the infrastructure, and the base of the cloud service. It provides the technology and memory for clouds for example. Vertical Services - government services, cloud entertainment, cloud publishing and online ad networks, cloud healthcare, and cloud telecommunications. These vertical services are basically what we use the cloud services for, which field they are in, and how they are used. Define each layer of services. Infrastructure as a Service (IaaS) - This is a service usually from outsourcing done by an organization so that the actual infrastructure to hold the storage, hardware, and other components are stored elsewhere. Why is bandwidth important? Internet bandwidth will drive the popularity of cloud services in the country, as businesses and consumers will demand more services as bandwidth increases. Speedy network reliability is needed for "megabit-per-second" services.

1. Identify the area of impact the scenario relates to. Business and Employment 2. Identify the main stakeholders to the IT system. Amazon and companies using Amazon's cloud service 3. Identify one ITGS social/ethical concern in the article Reliability 4. Describe ITGS terminology and systems. The hardware used in this situation is the servers used to host information for companies. Amazon's cloud model is used by the connecting to the internet network. The Availability Zones are the zones that according to Amazon, are distinct locations that are engineered to prevent failures in other Availability Zones. Amazon Web Services (AWS) - Amazon's web service that provides companies with infrastructure web service platforms in the cloud. Amazon's Elastic Computer Cloud (EC2) - A web service that provides resizable compute capacity in the cloud, designed to make web-scale computer easier for company developers. Amazon's Elastic Block Store (EBS) service - this service provides block level storage volumes for use with Amazon's EC2 instances. The EBS volumes are off-instance storage that is independent from the life of an instance. http://aws.amazon.com/ 5. If possible, describe a solution to the concern (issue). A solution to the reliability concern is for businesses and companies to filter out what they plan to put on Amazon's cloud services, and what to keep in their private network within their control. Balancing the two would beneficial and can prevent a lot of damage that a failure of a server may do the company as well as its files and data stored in the cloud. Amazon explaining how their cloud service actually works and have it backs up everything should be able to calm down businesses, and regain their trust again once everything is back up and running again.

Explain: NoSQL non-relational database Explain the advantages of CouchDB's noSQL . May 9 soo

 Explain  NoSQL= NoSQL is a category of database engines that do not support the SQL (Structured Query Language) in order to achieve performance or reliability features that are incompatible with the flexibility of SQL. - http://stackoverflow.com/questions/4154635/what-is-nosql-what-is-purpose-of-nosql-where-can-i-get-sufficient-material-on-n  Non-relational database= a non-relational database developed by Damien Katz, now the chief technology officer for Couchbase. The company claims that Mobile Couchbase is the first non-relational, or NoSQL database, built for iOS. - http://stackoverflow.com/questions/202819/what-is-an-example-of-a-non-relational-database-where-how-are-they-used  Explain the advantages of CouchDB's noSQL - CouchDB and noSQL architecture has a number of advantages that make it attractive to iPhone applications developers, the company asserts. - CouchDB= Efficient use of working memory, Amount of storage space (takes up relatively minimal, under 20 megabytes download size limit imposed by many people CouchDB's NoSQL has advantages such as its synchronization capabilities with minimal coding. Data can be automatically synchronized across a network. The app can store data created on the phone itself, all the while also synchronizing the same data with a cloud service or a data center. The storage space taken up by CouchDB's NoSQL has efficient use of working memory. When it is embed in an app, it can still keep the app to be under the 20 mb download limit, and doesn't drain the battery.

Describe NoSQL and its purpose. Explain how it is used differently than MySQL. M12 jan30 az

Describe NoSQL and its purpose. NoSQL is a highly scalable and reliable non-relational databases designed to maintain high performance and to be highly cost efficient for workloads of any scale, from the smallest to the largest internet-scale applications. It is also used to build a new kind of database for "unstructured" information that comes spilling off the Internet with each passing second. It is capable of handling large amounts of data du to the fact that they use flash storage rather than traditional spinning disks. These solid-state drives can provide single-digit millisecond response times. Explain how it is used differently than MySQL. MySQL database is a relational database that stores data in neat rows and columns, and it's designed to run on a single machine, while NoSQL database can store data in a more flexible way and is designed to scale across a very large number of machines. "SQL databases are like automatic transmission and NoSQL databases are like manual transmission. Once you switch to NoSQL, you become responsible for a lot of work that the system takes care of automatically in a relational database system. Similar to what happens when you pick manual over automatic transmission. Secondly, NoSQL allows you to eke more performance out of the system by eliminating a lot of integrity checks done by relational databases from the database tier. Again, this is similar to how you can get more performance out of your car by driving a manual transmission versus an automatic transmission vehicle." http://stackoverflow.com/questions/2559411/sql-mysql-vs-nosql-couchdb

Gmail tips summary Basically, Gmail gives you a plenty of space to storage for example 7 gigabytes for free, which is already a lot. Even though you are running out of the space. You are able to get more spaces for just $5 per year, is quite cheap. What is so good about Gmail? The most useful feature is that you can link your other email account, AOL, Yahoo, or Hotmail right away to your Gmail, which means you do need to open up many email to check your Inbox. a) You can set up filters to skip the Inbox and go right to the folder or a trash can. b) If you happen to find some information that is quite old, Gmail uses GooGle search engine to allow you to find it easily. c) Gmail offers " canned message" You can set up a filter so that a certain type of email always gets a canned response.

summary woo nov 22

This article is about the potential significance of mobile and cloud computing. IBM proposes that there will be more software for Smartphone and tablets than traditional office system in 2015. They say that it is important to be able to adapt new technology, especially cloud computing, computing in which services and storage are provided over the Internet instead of in-house networks, which will eventually play a key determent in all profession in the future. IBM people claim that "A lot of companies we work with today are not only taking advantage of mobile but are putting IT (Information Technology) skills in the hands of all kinds of professionals," and predict that necessary job skills will include ability to handle software applications. Mobile and cloud computing were also ranked the hottest technology career opportunities next year, in a survey. Mobile applications sales are predicted to expand from 6.2 to 30 billion dollars by 2013.

Why is cloud computing gaining widespread adoption? Why is it cheaper? Describe saas Describe the Tangerine example. What kind of customers does salesforce target? How does cloud computing encourage collaboration? march 17 soo

1.Why is cloud computing gaining widespread adoption? Cloud computing is gaining widespread adoption because cloud computing enables users to connect to corporate data and applications via online enabled devices. It offers the complexities and unique requirements of sophisticated applications, yet delivers them in less time and with lower startup costs. 2.Why is it cheaper? Cloud computing is cheaper cost when they deliver IT systems because businesses pay for only what is used and by that they could reduce the amount of cost in capital and operating cost. 3.Describe SaaS. SaaS stands for Software as a Service. Users who use services that is net-based are charged for the software they used, either as a subscription or as a pay-as-you-go basis. It is basically charging the service costs for the software that the users are utilizing. 4.Describe the Tangerine example. Tangerine is a company that sells enterprise version of Google mail and applications. These applications uses Gmail or Google's online document systems as an interface. Users who use Tangerine are charged a subscription fee for the usage of Tangerine. 5.What kind of customer does sales-force target? Salesforce is targeting people who actively use clouding computing system. Basically, it could be individual people but mostly many huge companies are using clouding computing to work efficiently. Also this system could save the money for the storage systems. 6. How does cloud computing encourage collaboration? By using user-friendly services like Facebook rather than conventional e-mail, feeds rather than memos, a touch-based system rather than a click-user interface, a push-based information system rather than pull or browse, location-based technology rather than unknown locations, and web service/HTML rather than Windows or Mac.

Describe the two issues that came up from the technical problems that interrupted computer services provided by Amazon. Why is the cloud model gaining popularity? List the problems that companies reported. april 28 az

1) Describe the two issues that came up from the technical problems that interrupted computer services provided by Amazon. One of the issues is that Amazon need to reconsider the contracts that cover cloud services such as how much to pay for backup and recovery services, including paying extra for data centers in different locations. The reason for this is because small businesses are less apt to pay for extensive backup and recovery services. The second issue would be many companies are relying too much on remote computers that are beyond their control. So they need to reconsider that also. The technical problem that interrupted computer services provided by Amazon told its customers and users that there may be a reliability problem with Amazon's service in online computing in the cloud. Companies and businesses operation network now revolves a lot around these remote network systems, so this also affects how companies will reconsider their use of exporting their files and data as opposed to keeping them within the company walls. 2) Why is the cloud model gaining popularity? Because owning a data center is high maintenance and therefore expensive. By using the cloud model, companies are avoiding the costs and headaches of running their own data centers. They just simply tap in, over the Web, to computer processing and storage without owning the actual machines or operating software. Businesses can also save their time by outsourcing to the cloud to save having to keep track of running their own data centers. 3) List the problems that companies reported. ( Unable to access data Service interruptions Sites being shut down

Are any corporate databases and networks safe? Should consumers be wary about providing personal data online? How valuable is data stored online? May 11 soo

Are any corporate databases and networks safe? According to the article, they mentioned that no corporation databases are not completely safe and secure enough to protect personal information. There are too much false which makes network perfectly safe. It is very large storage and contains a lot of personal information. If the network is too big, they can't manage the network well and all the weaknesses will occur. The hackers will aim to hack the corporate databases because it has a lot of information therefore; it is not actually very safe. Should consumers be wary about providing personal data online? Yes, consumers should be wary about providing personal data online, because all services that store the online data are all under risk of being hacked, and the data compromised. Once the sensitive information is compromised, the user is more vulnerable to scam attacks through e-mails, as well as have their bank accounts or other user accounts online hacked. consumers should be a warning to be wary about providing personal data online because no corporate networks are frequently attacked by hackers and no matter how diligently their administrators work to protect them or how many protections are put n place, no network is perfectly secure. Even Sony' security systems are not perfect at all. Therefore, people have to be wary about providing personal data online How valuable is data stored online? Data stored online is very valuable, especially sensitive information such as ID numbers and bank/credit card numbers. Other personal data such as names, passwords, and security question answers are useful for hackers, and can be easily used for impersonation on other sites to hack into user accounts for further bad intentions.

Explain the issues that are in common with both Amazon and Sony? Explain the reasons that cloud computing will continue to grow? What could have prevented Sony from getting hacked? Describe: Rambo architecture Chaos monkey Explain the reason that data centers for cloud computing need backups? may 9 woo

1. Explain the issues that are in common with both Amazon and Sony? Issues that are in common with both Amazon and Sony are their reliability and integrity as well as its security. Amazon has just revealed that its Availability Zone in northern Virginia has failed to accommodate customers that were using their services. Sony's hack incident includes its network protection system to be unreliable. Also the security of Amazon's customer's data along with Sony's online users' data is at risk, as well as sensitive information linked to bank accounts. Both Sony and Amazon suffer a setback on their online reputation. Both companies have their servers down which affect a lot of their customers using their services. They both revived worries about the safety of storing and processing data over the Internet. The two crises have also raised questions about the speed and quality of information provided by tech companies when confronted with systems failures. This further links to the data integrity. Amazon users have said that some data may be corrupted or loss resulting from their sites crashing. Sony's users' accounts data may have been altered by unauthorized people. 2. Explain the reasons that cloud computing will continue to grow? Cloud computing will still continue to grow despite its recent incidents because the benefits users receive outweigh the risks that come with cloud computing. The outage suffered by Amazon has been rare. Also, managing one's own network is hardly a guarantee of reliability; it costs a lot of money and is high maintenance. Cloud computing provides another alternative that can save costs for businesses. Also, the recent incidents have proven that managing one's own network is not as reliable as some think considering protection issues and failure/crashes in the network itself. 3. What could have prevented Sony from getting hacked? Sony could have increased its protection system, as well as create random simulations in orde
